Att göra webbsidor tillgängliga för olika sorters enheter är ett område som har uppstått i och med smartphonens utveckling. Mängden enheter har under de senaste åren ökat stort och det är inte längre endast laptops och datorer som används. Då enheternas skärmupplösning skiljer sig krävs en anpassning beroende på enhet för att ge en bra användarupplevelse. För att identifiera tillgängliga tekniker har en kvalitativ undersökning genomförts. Undersökningen består av en genomgång av utvald litteratur samt intervjuer med utvecklare på företagen Nethouse och Laget.se utförts. Detta för att inhämta information om användandet av tekniker, undersöka om det finns något framträdande tankesätt samt undersöka för- och nackdelar med teknikerna. Slutsatsen är att alla tekniker har sina användningsområden eftersom de har olika styrkor och svagheter. Resultatet från denna studie presenteras som en genomgång av de befintliga teknikerna och deras potentiella användningsområden för att vägleda valet av teknik. / Making web pages available for different types of devices is an area that has arisen with the development of smartphones. In recent years it has become a major increase in units and there are no longer only laptops and computers that are being used. Since there is a size difference between the different devices there is need for adjustment depending on the device to provide a good user experience. The study was carried out as a qualitative study to identify available technologies. A review of available literature and interviews with developers at the companies Nethouse and Laget.se was conducted to obtain information on the performance of the techniques, if there is any way of thinking and if there is advantages and disadvantages of the techniques. The conclusion is that all technologies have their uses as they have different strengths and weaknesses. The results from this study are presented as a review of the existing technologies and their potential uses to guide the choice of technology.

Indiana University-Purdue University Indianapolis (IUPUI) / The Energy Monitoring Framework, designed and developed by IAC, IUPUI, aims to provide a cloud-based solution that combines business analytics with sensors for real-time energy management at the plant level using wireless sensor network technology. The project provides a platform where users can analyze the functioning of a plant using sensor data. The data would also help users to explore the energy usage trends and identify any energy leaks due to malfunctions or other environmental factors in their plant. Additionally, the users could check the machinery status in their plant and have the capability to control the equipment remotely. The main objectives of the project include the following: • Set up a wireless network using sensors and smart implants with a base station/ controller. • Deploy and connect the smart implants and sensors with the equipment in the plant that needs to be analyzed or controlled to improve their energy efficiency. • Set up a generalized interface to collect and process the sensor data values and store the data in a database. • Design and develop a generic database compatible with various companies irrespective of the type and size. • Design and develop a web application with a generalized structure. Hence the database can be deployed at multiple companies with minimum customization. The web app should provide the users with a platform to interact with the data to analyze the sensor data and initiate commands to control the equipment. The General Structure of the project constitutes the following components: • A wireless sensor network with a base station. • An Edge PC, that interfaces with the sensor network to collect the sensor data and sends it out to the cloud server. The system also interfaces with the sensor network to send out command signals to control the switches/ actuators. • A cloud that hosts a database and an API to collect and store information. • A web application hosted in the cloud to provide an interactive platform for users to analyze the data. The project was demonstrated in: • Lecture Hall (https://iac-lecture-hall.engr.iupui.edu/LectureHallFlask/). • Test Bed (https://iac-testbed.engr.iupui.edu/testbedflask/). • A company in Indiana. The above examples used sensors such as current sensors, temperature sensors, carbon dioxide sensors, and pressure sensors to set up the sensor network. The equipment was controlled using compactable switch nodes with the chosen sensor network protocol. The energy consumption details of each piece of equipment were measured over a few days. The data was validated, and the system worked as expected and helped the user to monitor, analyze and control the connected equipment remotely.
